Which physical security measure would be effective at preventing unauthorized access to a server room?

1. A fingerprint reader on the server room door

2. Open access policy

3. Security cameras only

4. Public entrance

The correct answer is: A fingerprint reader on the server room door

Implementing a fingerprint reader on the server room door is an effective physical security measure because it utilizes biometric authentication, which adds a layer of security that is more difficult to bypass than traditional access methods. Fingerprint readers ensure that only authorized personnel who have been registered in the system can gain entry. Biometric access systems generally provide a higher level of assurance compared to keys or access cards since fingerprints are unique to each individual. This measure not only helps in controlling who can enter the server room but also allows for better monitoring and accountability, as access logs can be generated, tracking who accessed the room and at what times. Such a system minimizes the risk of unauthorized access by exploiting the specific and irreplaceable nature of biometric data. This makes it a robust solution in protecting sensitive environments like server rooms, where the integrity and confidentiality of the data are critical. In contrast, the other options lack the security rigor needed in such sensitive spaces. Open access policies would inherently allow anyone to enter without verification, while relying solely on security cameras does not prevent access; cameras may deter, but they do not control entry. A public entrance poses a significant security risk by allowing unrestricted access to anyone, which would undermine the protection of the server room.
